First, let's appreciate the precise and technical nuance (emphasis added):
The Liberals and New Democrats signed an agreement on Monday to form an unprecedented coalition government, with a written pledge of support from the Bloc Québécois, if they are successful in ousting the minority Conservative government in a coming confidence vote...
The Bloc would not officially be a part of the coalition, but the new government's survival would depend on its support.
Then let's appreciate why sane people dismiss the Blogging Tories as ignorant airheads and insufferable retards.
I trust we've cleared this up for you.
